Porous Ceramic Ball 8mm 10mm 13mm 16mm 20mm

1.big surface area and free volume 2.Heat-resistance 3.ISO9001:2000... Application: Industrial Ceramic

Porous ceramic balls is also called filtering balls. It is made by make 20-30% pores inside the inert ceramic balls.

 

If the porous ball is set on the  top of a reactor, the impurities fail to be eliminated in former process could be adsorbed in the pores inside the balls, thereupon protect the catalyst and prolong the operating cycle of the system.  

 

As the impurities present in the materials are different, the user can select the product by their sizes, pores and porosity, or if necessary, add molybdenum, nickel and cobalt or other active components to prevent the catalyst from coking or poisoning.

Size      

NANXIANG Porous ceramic balls are divided into 12 grades by reference to Al2O3 content varied from 25% to 80%,and  every more 5% constitutes a grade, but 12 sizes by reference to the diameter, such as

 

 Φ3 ,Φ6 ,Φ8 ,Φ10 ,Φ13, Φ16 ,Φ20 ,Φ25 ,Φ30 ,Φ38 ,Φ50, Φ75.

 

The products in other grade and sizes can be designed and manufactured if to the users request.
